OFDM Turbo DeCodulation with exit optimized bit loading and signal constellations
We propose the combination of Orthogonal Frequency Division Multiplexing (OFDM) and Turbo DeCodulation (TDeC) – a multiple Turbo process consisting of iterative demodulation and...

Adjugate pairs of sparse arrays for sampling two dimensional signals
Sparse sampling with coprime lattice arrays was introduced recently in the literature. It has been shown that a dense coarray can be constructed from such a pair of arrays, and is...
